Osprey's Atmos 65 pack is a great thru-hiking, or week long trips pack. The Atmos 65 brings Osprey's lightweight AirSpeed Suspension, contoured mesh backpanel and waffle foam harness and hipbelt to multi-day backpacking. With a strong 10mm aluminum frame with titanium flex struts and thicker harnessing, you won’t be disappointed with the comfort of this well-featured pack.

The AirSpeed suspension makes the Atmos & Aura* Series like no other ultralight packs. The AirSpeed frame is 6005-T6 alloy aluminum with titanium struts providing flex in the middle. Unlike other mesh-tensioned backpanels that are simply flat panels suspended from four tensioned corners of an X-frame, this panel is 3D contoured to truly fit the shape of your body. All contact surfaces are either breathable mesh or perforated, molded waffle foam. Your experience is a pack fit with comfortable uniform body contact and no hot spots, whether your bagging a fourteener, hiking the AT or pulling your next 24-hour race.
